>Description:
If PKG_PATH environment variable is set, bootstrapping pkgsrc is failed
like the following.

   tstrap.tmp/pkg_install/info/pkg_info /tmp/bootstrap.tmp/sbin/pkg_info
   ===> Installing packages
   ===> running: (cd /srv/pkgsrc/pkgtools/bootstrap-mk-files && 
/tmp/bootstrap.tmp/bin/bmake  -DPKG_PRESERVE 
MAKECONF=/tmp/bootstrap.tmp/mk.conf install)
   ERROR: This package has set PKG_FAIL_REASON:
   ERROR: Please unset PKG_PATH before doing pkgsrc work!
   *** Error code 1

   Stop.
   bmake: stopped in /srv/pkgsrc/pkgtools/bootstrap-mk-files
   ===> exited with status 1
   aborted.


IMHO it makes sense to make this check on early stage
or even unset PKG_PATH variable directly in bootstrap script.
